Is there a relationship between type 2 diabetis and tinnitus?

Small vessel disease. One complication of diabetes is blood vessel disease. This can lead to narrowing and occlusion of arteries. There is a risk of occlusion of the end arteries of the cochlea which can lead to hair cell damage, tinnitus and hearing loss. If you have diabetes and tinnitus, get your hearing checked, see your doctor or endocrinologist about better blood sugar control to delay/prevent further damage.
